Kromschroder Spring 03089066

The Kromschroder Spring 03089066 is an original spare part designed for use in Kromschroder JSAV 50-100 safety shut-off valves. It operates within a pressure range of 190–400 mbar and is identified by its orange/yellow color. The spring is made from spring steel and comes with a warranty.

Parts of this type are selected by their pressure range and color coding, which must match the required set point for the application. The spring is typically fitted under a cap or inside the actuator housing, with preload adjusted by turning a screw or nut. Before ordering, verify that the pressure range and part number correspond to the device's documentation.

When springs of this kind fail, the valve may not open or close at the correct pressure, leading to unstable modulation or unintended lockout. Check the spring for deformation, breakage, or loss of tension, and compare its color and part number to the device's specifications.
